Driver Kit Update
$400 AA Battery Accident
This order was my first time using PCBWay and I am blown away by how seamless from end to end the entire process is! I love the technological process tracking, it’s funny, but it reminds me a bit of how some pizza places track the progress of your pizza. My order was accepted, manufactured, shipped and in my shop in no time at all!
The quality of the boards, through-hole plating, silkscreen, bottom side tinning, and everything is a definite A+. I received excellent communication and engineering cooperation from the beginning. Although there are other PCB manufacturers that I like, I am going to use these guys going forward! I’d recommend them for prototyping or production.
Open Source Advocate
I especially like that they encourage open source projects by allowing you to share your board designs, schematics, and project details after ordering. Here is the Hybrid Driver v1.3 in PCBWay’s project sharing section. They make it easy for others to order boards since all the Gerber files are already there and pre-approved. They even give a 10% back to the project creator. Check it out and take a look at there projects, there are some impressive ones. I like OpenReflow, a control board to convert a simple toaster oven into an accurate reflow oven for soldering SMD components.
The new driver boards look great. I like the high gloss black solder mask and the highly visible white silkscreen over it. The slots for the IGBT gate connections turned out great. The board edges are clean and completely burr free. The only mistake I’ve found is that I forgot to set the OSH logo font to vector, so it expanded a bit and overlapped the G2 silkscreen. I also tweaked a few device name silkscreen positions to improve visibility.
I’m waiting for the bulk orders of the VLA106-15242 isolated DC to DC converters and the M57962L gate drivers. After that, I’ll stuff the boards and get them in the ReactorForge to continue refining the firmware.
The First Kit
I’m planning on making the IGBT Driver (Hybrid Driver v1.3) the first complete kit. Of course, it will be standalone, apart from the rest of the induction heater. I’m ok with having the major components of the induction heater available individually as well as part of the whole machine kit.
I have never made a kit like this, but I am entirely confident that I can put together a great one. Still, this will give me the chance to test that confidence on a smaller scale. I’ve already established a supply chain for the parts and the PCB. What’s left is ordering consumables such as antistatic shielding bags, labels, and packaging. Then, of course, the written plans or instructions for the kit.
There has been a lot of confusion created by they way Patreon charges its patrons and paying creators. You can find the official information can here: https://patreon.zendesk.com/hc/en-us/articles/115005631963 And here is another excellent article on the topic by TechCrunch.
TLDR; The short version is, Patreon moved its credit card processing service fees from the creator to the patron. Because of this change, Patreon was able to lower the overall fee amount and give more to the creator. The fee amount is (2.9% + $0.35) for each monthly pledge.
Because I have worked on unique e-commerce projects, I understand the intricacies and complications of bulk credit card processing, multiple payees, and the associated charges and chargeback liabilities. However, I do not support Patreon’s decision, and I firmly believe there is a better solution. Because Patreon is a goodwill engine, I think this move is, for lack of better terms, just weird. In addition, I won’t personally be canceling any of my Patreon pledges. Nevertheless, as a patron myself and now a fledgling creator, I do hope that we see these processing fees moved back to the creator.
Other Support Options
Your support is much appreciated, but entirely voluntary. You may continue to make a small donation to support the project and website using Patreon. If you decide to cancel out of principal, I understand entirely. If you prefer I’ve added a PayPal button on the pledge page “Coffee” to enable you to make a small reoccurring monthly pledge that you can change or cancel it at any time.
Or you can send a one-time pledge. Please include a note to let me know it’s a gift and what made you decide to support ReactorForge!
I may add members only functionality to the website linked to Patreon PayPal as well, to mirror and even enhance the capabilities Patreon offers. But I’m not sure there is indeed a need for that yet, or possibly ever. Thank you all again for your support, be it monetary, intellectual, or constructive criticism. I value all of it!
ReactorForge Parts Delivery
I just received the first shipment of parts for building more ReactorForge induction heaters, 258 pounds worth. This component is of one particular importance and one I have settled on despite other possible changes I will be making to the design. Anyone care to take a guess what part this is?
This new rolling stand from SAMs club was perfect for holding the Reactor Forge, Bernard Weldcraft 3 gallon water cooler, extra bricks, and coils. I just need to replace the top plastic insert/mat with a piece of sheet metal.
High-level action plan:
- Publish existing mechanical specs, unit wiring schematic, core control board schematic, to Atmel C code to Github.
- Add my current issues and changes that need to happen to each of the above topics in Github for proper tracking.
- Work on those issues, changes, and improvements.
- Make the next version, test, refine, and repeat as needed.
- Work on BOM supply chain.
- Kit logistics: work on which parts will be preassembled and which will require user assembly.
- Create and publish a kit manual.
- First test kits for users, feedback, etc. etc…
